Genesis 13:2, 5, 10-11

Now Abram was very rich in livestock, in silver, and in gold.

And Lot, who went with Abram, also had flocks and herds and tents

And Lot lifted up his eyes and saw that the Jordan Valley was well watered everywhere like the garden of the LORD, like the land of Egypt, in the direction of Zoar. (This was before the LORD destroyed Sodom and Gomorrah.) So Lot chose for himself all the Jordan Valley, and Lot journeyed east. Thus they separated from each other.
